To all whom 'it may concern:

Be it known that I, WiLLIAM D. Lower, a citizen of the United States ofAmerica, residing in the city of St. Louis and State of Missouri, haveinvented certain new and useful Improvements in Car-Bolsters andDraft-Riggings, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My 1nventionrelates toa combined car body bolster and draft rigging andhas for its object to incorporate in a construction of this character alurality of holsters connected to each ot 1er by a bottom or centerbearing plate for the purpose of distributing the loadof the car body tobetter advantage than in the use of a single bolster and also for thepur ose of affording stronger arrangement or the connection between thebody holsters and the trucks of thecar.

Fi ure'Iisatop or lanviewoflnycombined lnultlple bolster an draftrigging. Fig. II is-an enlarged View in part a front elevation of thecentral part of the forward bolster and in part a cross section taken online II-II, Fi I, through the draft bar, Fig. III is an enIarged rearelevation of the central portion of the rear bolster'. Fig. IV is anenlarged top or plan view of my multi le bolster and draft rlgging withthe forwarc bolster shown partly 1n horizontal section.. Fir.' V is anenlarged section taken transverse y through the' multiple bolster andlongitudinally through the draft rigging.

Referring first to my multiple holster,- 1 designates the rear bolsterwhich is provided at its lower side with a recess 2 that receivesA amember to be hereinafter referred to.

.3 is the forward bolster that is provided Wlth a recess 4 thatreceives-the draft har as will hereinafter more fully appear. Thebolster 3 has integral with lts top portion ain the use 'of the rigging,delivered to the web 5 of the forward holster through the medium of thedraft spring that is'rearmost relative to the direction offmovernent ofthe draft bar.

10 designates a bottom connecting late or member that unites lthe lrearand orward holsters. in the holsters and is detachably connected to saidholsters by bolts 11, see Figs. II to IV inclusive. The connecting plateis provided with a center bearing 12 adapted to rest upon the truckbolster of a car truck and through end of the connecting plate whichenters into the recess in the forward bolster 3 serves to retain thedraft rigging, previously described, in said recess and centrallylocated u on the top of this end of the connecting p ate is a boss 13that enters into the lower end of the web 5 forming a part of theforward bolster and serves as a medium forstaying the lower end of saidweb in order to which it is subjected by the draft rigging. It will heseen that while the connecting late-.I0 serves as a member for unitingthe two holsters herein described and as a member for the reception ofthe king-bolt and the center bearing .between said holsters, it isdetachahly connected to the holsters and may he readily separatedtherefrom for the pur ose of permitting the removal of the dra 'trigging from the bolster whenever-circumstances, such as thenecessityfor repairs ofthe draft rigging, necessitate the removal ofsuch rigging from the bolster.
